 This is done through the use of dynamic herbaceous fuel beds, where the “live herbaceous load is transferred to dead as a function of the live herbaceous moisture content.” The use of a curing coefficient allows more realistic modeling of fire behaviors in herbaceous fuel beds.Furthermore, these models aim to move away from the correlation between vegetation type and fuel bed characteristics.For example, the original ‘chaparral’ model becomes the ‘heavy load, tall brush” model.
